Quickly Monitor Your System


The BACnet Building Controller Small Display (BBC-SD) is a compact, wall mountable, and addressable network display device for MS/TP-based networks that enables users to quickly monitor their HVAC system, and easily make changes to the way their building is controlled.

The BBC-SD features a touchscreen interface with permission-based menu icons allowing for simple navigation to read and write values, view alarms, grouped data, and point descriptions. The BBC-SD is easily configured via the Windows® based BBC SD-Pro™ utility.
